In this embodiment, after the script generation unit determines the target geographic analysis task and receives the relevant task parameters, the script generation unit may generate a corresponding function script file according to a script file writing rule.

For example, the script file can be written by using an R language or a Python language, and the script file writing rule is the same as a common script file writing rule, and the normalization setting can be performed in advance. The R language script for drawing the unitary linear regression graph of the vegetation coverage and the temperature is as follows:

# read File

data=read.csv("d:\data1.csv")

library(ggplot2)

# analysis chart Axis tag information

pLab = 'vegetation coverage, temperature'

In this embodiment, the interface identifier is an identifier of an interface of each item information in the DAS document, and the DAS document implants the interface identifier into the script file to transfer information and parameters of the function script and the DAS document.

In this embodiment, in order to implement the invocation of the user-defined function by the DAS and implement the bidirectional transfer of the parameters between the DAS and the target task script, the interaction between the DAS document and the background system needs to be implemented through the computation process table in the DAS document, and therefore, the input column information, the control column information, and the output column information in the computation process table need to be identified.

IN this embodiment, the information provided by the input field is a layer or a table for processing, and may include one or more layers or data tables, and for example, "[ IN ]" may be used as an identifier. Where x represents 1 to N, N being the number of entries.

The information provided by the output column is the result of keyword processing, including filling OUT the form serial number, the layer and the data form, and for the expansion of the user-defined function, only the layer and the data form need to be processed, and for example, "[ OUT ]" may be used as an identifier, where x represents 1 to N, and N is the number of output items (excluding the form serial number).

The control column information comprises keyword description data and keyword control parameters, and the keyword description data comprises keyword Chinese brief description, keyword input and output and control parameter description information. Illustratively, the keyword chinese brief description uses "# [ description ] as an identifier; the keyword input/output and control parameter description information uses "# [ keyword ] as an identifier. The keyword control parameter describes a parameter used when the keyword is specifically called, and is divided by the symbol "|", and each parameter is identified by [ P1], [ P2], [ PN ].

In this embodiment, the output object information refers to information of a processing result output in the script, and corresponds to the output object information and the output interface identifier according to the interface design rule of the DAS method.

Illustratively, for the function script in S11-1, the output information is a picture file (which may include jpg, bmp, emf, pdf, etc. formats), denoted by F, and the interface identifier "[ OUT1 ]".

S12-4: and setting a control parameter interface identifier according to the control parameter information of the target task script file.

In this embodiment, the control parameter information is information of each parameter for controlling the script function, and each control parameter is respectively corresponding to the control parameter interface identifier according to the design rule of the method interface of the DAS.

Illustratively, for the function script in S11-1, the control parameters are: the picture names | XName | YNAme | XLAb, YLab | PointColor, LineColor, the interfaces are identified as "[ P1 ]", "[ P2 ]", "[ P3 ]", "[ P4 ]" and "[ P5 ]", respectively.

In this embodiment, according to the function script and the interface setting rule of the key word method of the DAS, corresponding interface identifiers are set for the function identifier information, the input object information, the output object information, and the control parameter information in the script, so that the DAS can perform information transfer according to the interface identifiers and various parameters in the script, and fill in the corresponding key word information in the calculation process table.

S13: and generating a corresponding interface script file according to the interface identifier and the target task script file.

In this embodiment, the interfacing script file is a script file obtained by implanting an interface identifier into the target task script file.

In this embodiment, after the interface identifier of the function script is designed according to the interface design rule of the DAS, the interface identifier needs to be embedded into the target task script file, and the DAS document performs parameter transmission with the script file through the interface identifier.

# [ Explanation ] univariate Linear regression analysis

# read File

data=read.csv("[IN1]")

library(ggplot2)

# analysis Diagram Axis tag information

pLab="[P4]"

# analysis chart color information

pColor="[P5]"

# Process Axis Label information and color information

pLab<-strsplit(pLab,",",fixed = TRUE)

pColor<-strsplit(pColor,",",fixed = TRUE)

# plot analysis

ggplot(data,aes(x=[P2],y=[P3]))+

geom_point(pch=17,color=pColor[[1]][1],size=2) +

geom_smooth(method="lm",color=pColor[[1]][2],linetype=2) +

labs(title="[P1]",x=pLab[[1]][1],y=pLab[[1]][2])

# preservation analysis chart

And determining the file information of the script file according to the user-defined keyword.

For example, referring to table 2, table 2 is a calculation process table according to an embodiment of the present application, and as shown in table 2, the calculation process table includes a step column, an operation description column, an input column, an operation column (control information column), an output column, and a description column. The user's target geographic task is to perform univariate linear regression on vegetation coverage temperature and temperature data of N sampling points in a region and draw an analysis graph, in order to implement the function and expand custom keywords, after storing an interface script file in a DAS specified directory, inputting corresponding parameters in a calculation process table, mainly inputting "vegetation and temperature" in an input field, adding the custom keywords "KX _ MyKeyWord (RModel 1/univariate linear regression. R | vegetation coverage and temperature univariate linear regression | VALUE1| VALUE2| vegetation coverage, temperature | blue, green)" in an operation field, and inputting "[ univariate linear regression statistical chart ] tjt. This completes the pre-call setup.

Claims

1. A method for extending a custom function based on DAS is characterized in that the method comprises the following steps:

according to interface identification setting rules of the DAS, obtaining an interface identification corresponding to the target task script file;

2. The DAS-based custom function extension method of claim 1, further comprising:

generating keyword description data of the target geographic analysis task in a control information column in the calculation process table according to the parameter information in the interface script file;

3. The DAS-based custom function extension method of claim 1, wherein the generating of the corresponding target task script file according to the target geographic analysis task comprises:

and debugging the function script file to obtain the target task script file.

4. The method of claim 1, wherein the obtaining of the interface identifier corresponding to the target task script file according to the interface identifier setting rule of the DAS includes:

5. The DAS-based custom function extension method of claim 1, wherein the generating a corresponding interfaced script file according to the interface identifier and the target task script file comprises:

6. The DAS-based custom function extension method of claim 1, wherein the invoking the interfacing script file by a custom keyword to obtain an analysis result of the target geographic analysis task comprises:

determining the file information of the target task script file according to the control parameters of the user-defined keywords;

7. A DAS-based custom function extension apparatus, comprising:

8. A computer readable storage medium having stored thereon a computer program, which when executed by a processor, performs the steps of the DAS-based softfunction extension method according to any of claims 1 to 6.
